Application filed May 3,

To all w hom t may concern Be it known that I, ALnssANDRo LnA'rI, a subject of the King of italy, residing at Milan, Italy, have invented new and useful Improvements in Cooking Ranges, of which the following is a speciiication. i

The present invention relates to cooking ranges and has for its object an improved cooking range adapted for any solid fuel, whether in lump or in dust form.

The main features oi' the invention consist in the rational combination of the various part-s and in a special arrangement or valve, by means of which an upward or a downward draught can be obtained at will according it is or is not desired to utilize the oven arranged in the lower portion, the oven being heated more or less as may be convenient or not being heated at all.

ln the annexed drawings:

Fig. 1 is a vertical section of the appa ratus;

Fig. 2 shows the same apparatus, partly in section and partly in outside view at an angle of 90 with respect to Fig. 1.

The apparatus comprises a lower chamber 1 forming its base, the chamber bottom 2 and sides 3 being preferably in practice lined with good non-conducting material. Inside the chamber 1 a metal7 preferably sheet metal, case t is provided, whose front 5 is fitted with a door 6. Between the outer chamber 1 and the inner case et an empty space is lett for the circulation of the hot gases.

On the case or oven l an angle collar 7 is mounted, the collar being an easy iit on a cylinder 8 mounted on the base and hinged to an operating rinthrough members 9. .ln the collar 7 slots pi and 7 are formed.

In the top portion of the oven a circular ceiling 11 is provided, the same being itted with slots 12 and 12 corresponding to the slots 7 and 7". In the plate 14 oi" the cover 11 a central aperture 15 is formed which serves to connect the hollow inside space of the cover to the inside of a stove or combustion chamber consisting of a cylindrical sheet metal box 16 and a frame 20 arranged therein on a tripod 19.

In the top portion of the cooking range a water kettle 22 is arranged, whose inlet 23 and outlet 23 may also serve as connections tor the piping of a thermosiphon.

In the top plate 24; are provided, in the Specification of Letters Patent.

usual way, apertures fitted with rings 25 and covers 26.

A sliding box or drawer 27 arranged above the oven serves as ash-pit and may also be filled with fuel when the oven is directly heated. A door 28 is provided in the drawer 27.

The smoke stack 29 is connected to the chambers 8 and 1 respectively by means of pipes 30, 31 iitted with swivel dampers 32, 33 of which Se, 35, 36, 87 make up the actuati ng gear.

Then it is desired to simultaneously heat the upper portion and the oven, the collar is partly rotated, by means of a handle a0 connected at eil as shown, so as to close the slots 12 and open the slots 12. Air is then admitted through the door 28 and through the apertures 15, 18, passes through the frame 2O and feeds the combustion at 38; the combustion gases accordingly impinge against the upper portion of 24 in the chamber 2l, then against the sides of the oven 4 and go through pipe 31 to the stack 29. In that case the swivel damper 33 is closed and 32 open.

By bringing the collar 7 into the position shown in Fig. 2, that is to say by so operating it as to open the slots 12 and close the slots 12', and by closing the door 28 and opening the top aperture 26, air is let in at 26, gets into the frame 2O where it feeds the combustion and after this enters the chamber 1 through the apertures 18, 15, 12 and inally gets into the pipe 31. ln, this case the oven, and the oven alone, will be intensely heated.

lf, instead, it is desired to heat the top portion alone and not the oven, it will sutlice to open the door 28 and the swivel damper 33 as indicated with' dotted lines in Fig. 1.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, what I claim is:

1. A cooking range comprising a lower chamber, an upper chamber having a central opening in the bottom, an oven in the lower chamber and spaced from the top, bottom and side walls thereof, Smoke escape ducts leading from said chambers and each having a damper, a combustion chamber in and spaced from the side wall of said upper chamber, a removable closure for the top of said upper chamber, and means to establish uncoznnumieeton between the bottom of the combustion chamber and the lower chamber and between jthe latter and the upper chamber et will.

2. A cooking range comprising e lo-Wer chamber, an upper chamber having a eentrnl opening; in the bottom, im oven in the lower chamber und spaced from the top, bottom and side Walls thereof, smoke escape duets lea-cling; from seid chambers and each having a damper, Ineens to reversely Slmultaneonsly operate said dempers, :roombuston chamber in and spaced from the Side ALESSANDRO LEATI.
